ZILLTEK · DC-DC Converters · TSOT-23-6L
ZTP7193YH from ZILLTEK, in a TSOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | BOOT | input | High-side gate drive boost input; a 0.1µF or greater capacitor from SW to BOOT powers the high-side switch, with BOOT limited to VSW-0.3V to VSW+6V. |
| 2 | GND | power_in | Ground reference for the controller and power stage; connect GND to a large copper area to cool the chip. |
| 3 | FB | input | Feedback input that senses the output through a resistive divider and regulates to a 0.6V threshold (feedback over-voltage threshold 0.72V); keep feedback connections short and direct. |
| 4 | EN | input | Enable input that turns the regulator on when driven high (rising threshold 1.22V typ) and off when driven low (falling threshold 1.12V typ); pull up with a 100kΩ resistor for automatic startup. |
| 5 | IN | power_in | Power input supplying the IC and the step-down converter switches, specified for 4.5V to 18V with absolute maximum of -0.3V to +19V; bypass to GND with a suitably large capacitor. |
| 6 | SW | power_out | Power switching output node that feeds the output LC filter; absolute maximum is VIN+0.3V, and a capacitor is required from SW to BOOT. |
